USE
The new generation of POWERCIAT LX water chillers
offers an optimal solution to all the refrigeration applications
encountered in the air conditioning or industrial process.
This range is designed with the latest generation of
components : accessible hermetic twin screw compressors,
modulating capacity control, communicating control and
management by Xtra Connect microprocessor, components
optimized for the ecological refrigerant HFC 407C.
This range is also proposed with an integrated hydraulic
module : POWERCIAT LXH. This one includes all the
elements required for a right operation of the unit :
buffer tank, expansion vessel, single or twin pump, air vent ,
pressure relief valves , shut off valves , manometers...
Units in accordance with EN 60-204 - EN 378-2 regulations
and directives :
- Machines (98/37 CEE) modified
- CEM (89/336 CEE) modified 92/31 CEE - 93/68 CEE
- Low voltage (73/23 CEE) modified 92/31 CEE - 93/68 CEE

ADVISES FOR INSTALLATION
■ Location
POWERCIAT LX
■ The POWERCIAT packaged units LX - LXC and LXH are
designed for outdoor installation.
■ Hydraulic connections
■
A free space of 2 meters around the unit is necessary for
a good air circulation and maintenance.
■
Choose the location in order to respect environment
(Acoustic level, etc,...)
■
The sound level problems must be analysed in detail
So, before installation of the unit, study the best position, if
necessary with a sound technician.
If necessary, install the unit on ant-ivibration mounts and
equip the hydraulic pipes with flexible connectors
(recommended equipments)
■
The hydraulic connections must be made following good
engineering practice
■
Plan all the necessary accessories for an hydraulic
circuit :
- Expansion vessel
- Drains at low points
- Shut off valves
- Air vent at high points, etc.
- Make sure that the installation water contents is sufficient
- Plan, if required, a buffer tank
■ Electrical connections
■
All the indications concerning electrical connections are
mentioned on the wiring diagram delivered with the unit (they
must be respected).
■ Commissioning
■
In accordance with our commissioning and maintenance
brochure
■
These connections must be made following good
engineering practice and in accordance to the norm in force.
■
Leave the control auxiliary circuit under voltage to allow
operation of the crankcase heater and the antifreeze heater
(option)
■
The customer electrical supply line must be fitted with a
circuit breaker protection (to be supplied by the customer)
■ Maintenance
■
In accordance with our maintenance brochure
■
Take out a maintenance contract
POWERCIAT LX - LXH - LXC
■ Antifreeze protection
■
If there is a risk of freezing :
a - either supply evaporator antifreeze protection option (LX
model) or evaporator antifreeze protection + hydraulic
equipment option (LXH - LXC models) if installation runs with
pure water
b - or protect the installation with glycol concentration
c - or drain the installation
NOTE : With the antifreeze protection, the unit is not
protected against freezing anymore if there is an electrical
supply failure.
